There will be always some applications which will be processed very fast and some, which due to various reasons will take forever (not trying to justify IRCC here).some applications are processed at lightening fast speed whereas, others are just ignored completely.
It seems like most applications from July 2022 onwards are progressing quite fast - most have MEP and BIL within around 2 weeks and after that it's impossible to predict how long it will take as every application is different.
But I do feel for those who've been stuck in a loop since 2020.
